Abstract
A memory storing public and confidential information is removably connected to a host device. General information on data stored in memory devices is accessible to the host device without authentication. Only a portion of confidential information stored in the memory device is accessible through the host device to an authenticated entity, where the entity has access rights to such portion. The entity is not able to access other portions of confidential information to which it has no rights. The public and confidential information is stored in a non-volatile storage medium, and a controller controls the supply of information. Preferably, the non-volatile storage medium and the controller are enclosed in a housing.
